Mark 3 In-Line ASME (ANSI) B73.2 Vertical In-Line Chemical Process Pumps Without Equal Designed to exceed ASME (ANSI) B73.2 criteria, the Durco Mark 3 In-Line is more than a spacesaving chemical process pump. It offers improved pump reliability and extended mean time between planned maintenance (MTBPM) through these exclusive features: Standard Mark 3A power frame with micrometer impeller adjustment Optional ANSI 3A power frame with three-year MTBPM guarantee The unique reverse vane impeller with consistent, repeatable performance SealSentry seal chambers including models with flow modifiers The unique C-Plus precision motor and pump shaft alignment system Broad parts interchangeability with standard Mark 3 horizontal pumps Complete menu of mechanical seal options, including advanced gas seal technology, to best meet application needs A wide array of options and accessories for extended MTBPM and improved safety Primary Industries Served Chemical processing Hydrocarbon processing General industry Complementary Pump Designs Depending upon application requirements, Flowserve can also provide these pump designs: HW ISO 13709/API 610 compliant in-line MSP low flow, high head in-line with variable frequency drive Mark 3 ASME (ANSI) horizontal standard CPX ISO horizontal standard PVML ISO 13709/API 610 compliant, in-line with multi-channel diffuser MSP Mark 3 Standard HW 3
Mark 3 In-Line ASME (ANSI) B73.2 Vertical In-Line Chemical Process Pumps The Durco Mark 3 In-Line ASME (ANSI) process pump delivers extended pump life, ease of maintenance and safety in addition to reliable, efficient performance. This space-saving pump has broad application in chemical and hydrocarbon processing as well as in general industry for services including: Chemical transfer Heat transfer Liquid gases Storage Water Washdown and cleaning Condensate return Light slurries Operating Parameters Flows to 370 m 3 /h (1630 gpm) Heads to 230 m (755 ft) Pressures to 24 bar (350 psi) Temperatures to 370 C (700 F) Motor sizes to 110 kw (150 hp) C-Flange Adapter is precision machined to provide fixed motor to pump angular shaft alignment within 0.001 mm/mm (0.001 in/in). Adjustable Parallel Alignment of motor to pump shaft to within 0.05 mm (0.002 in) reduces coupling loads to improve pump, seal, motor and coupling life. Broad Choice of Coupling Designs due to precisely adjustable parallel and fixed angular motor to pump shaft alignment. Conventional spacer coupling type is standard. Open Motor Adapter permits ready access to seals and seal flush connections for reduced maintenance time. 4
Mark 3 Power Ends are completely interchangeable with Mark 3 standard pumps and offer: Double-row angularcontact outboard and single-row deep-groove inboard bearings for excellent axial and radial load support Double-lip oil seals Micrometer shaft adjustment for precisely accurate impeller-to-seal chamber setting and reduced maintenance time Reduced Parts Inventory due to interchangeability with horizontal Mark 3 Standard power ends Standard adapters Standard shafts Standard seals Standard hardware and fasteners Superior Pipe Load Capacity as loads are transferred through the casing, eliminating misalignment of the pump and motor. Streamlined Suction Nozzle eliminates turbulence for low NPSH requirements.. Flange Connections are available in ASME Class 150 or Class 300 with flat or raised faces. Pump Bearings carry impeller loads not the motor. With the largest shaft and bearing components available in standard ASME (ANSI) pumps, the Mark 3 offers greater load-handling ratings and deflection comparisons (< 0.05 mm [0.002 in] deflection at seal faces) for extended MTBPM. Regreasable bearing lubrication is standard. Coupling Guards are available in steel, aluminum or polycarbonate materials to ASME B15.1 requirements. Design Features Micrometer Impeller Adjustment Impeller clearance setting to rear cover in 20 seconds No shims or wear rings In-shop or in-field adjustment Reverse Vane Impeller Low, predictable seal chamber pressure and thrust loads for longer seal and bearings life Lowest overall NPSH required of any standard pump Rear cover plate wear surface instead of the more expensive casing In-shop or field impeller and mechanical seal setting Repeatable performance assurance Advanced Mark 3 Seal Sentry Design Technology Extend seal life Self-flushing Self-venting Self-draining Reduce maintenance and repair costs Permit use of less expensive seals and flush plans Flush plans 11, 32, 52, 53, etc. can be eliminated Increase MTBPM Provide a safer environment for personnel Available in multiple designs to precisely match application needs Tapered bore - FML (large gland bolt circles) - FMS (small gland bolt circles) - FMI (integral gland) Cylindrical bore - CBL (large gland bolt circles) - CBS (small gland bolt circles) Flow Modifiers Extend Mechanical Seal MTBPM Flow modifiers redirect flow from circumferential to axial Balanced flow with low pressure drop in the chamber helps keep solids in suspension, minimizing erosive characteristics of the process A mechanical seal creates a centrifuging action away from its parts and into the returning flow path of the process liquid Solids and slurry merge in the returning flow path and are flushed out of the seal chamber 5
